🔧 What Happens During Check Engine Light Diagnosis

1. OBD-II Code Retrieval
Technicians connect a professional OBD-II scanner to your vehicle’s diagnostic port to access fault codes stored in the engine control unit. These codes pinpoint issues like misfires (P0300), oxygen sensor faults, loose gas cap, and more

2. Live Data Analysis
Beyond code reading, they monitor live parameters (e.g., fuel trim, sensor readings, RPMs) to understand the severity and context of the fault

3. Physical Inspection of Affected Components
Based on the codes, the technician inspects components like ignition coils, spark plugs, catalytic converter, gas cap seal, or vacuum lines.

4. Clear Codes & Confirm Repair
After repairs, the system is reset. Techs check if the light returns during test drives to confirm the issue is fully resolved
